To solve the expression $2 + 5(8 - 5)$, follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)):

1. Parentheses: First, solve the expression inside the parentheses: $8 - 5 = 3$

2. Multiplication: Next, multiply 5 by the result from the parentheses: $5 \times 3 = 15$

3. Addition: Finally, add 2 to the result from the multiplication: $2 + 15 = 17$

So, the solution is $\boxed{17}$.
